Hey 👋 we are Luiz and Diogo, the founders of Exa Energia.
Overview
Exa is a marketplace bringing liquidity to energy generators, while buyers negotiate better prices and secure future capacity. We're starting in Brazil, where supply exceeds demand.
Ask: Intros to early stage funds that write $1M+ checks and have invested in energy. Reach us at [email protected], or DM Luiz on LinkedIn or @diogomafra on X.
The problem
The low-voltage energy market of Brazil moves USD 100 billion per year and still runs on fax-era technology. Opaque prices, paper guarantees, manual meter reading and thin observability means nobody sees the grid in real time.
Technology skipped this market, phone calls, spreadsheets and trust held together by PDFs.
Opacity hits market participants with unmatched supply and demand, resulting in wasted generation (curtailment) and unnecessary price premium.
Additionally, for half of the Brazilian energy market, there isn't even a market. Generators must find themselves their consumers or trust on small energy distributors.
Our solution
Exa is the energy market for distributed generators, where they meet consumers directly and we handle the utility back-office behind it: contracts, switching, billing. Consumers pay less, generators sell more, and neither side touches the paperwork.

Vision
People think that to get to energy abundance, we just need more energy. But that's far from the truth. Brazil already has more energy than it consumes and yet, we pay one of the highest prices in the world. To get there, we need to make energy flow seamlessly from buyer to seller, every second. Once we get there, then we'll be able to unlock energy abundance.
